我们表明，在脉冲电检测磁共振（pEDMR）信号调制结合锁定检测方案可以减少一个数量级的低频噪声水平，此外还消除了微波诱导的非共振背景。这是示范性地证明了在磷掺杂硅的自旋回波测量。信号的调制通过循环pEDMR中用于自旋状态读出的投影脉冲的相位来实现。
We show that in pulsed electrically detected magnetic resonance (pEDMR) signal modulation in combination with a lock-in detection scheme can reduce the low-frequency noise level by one order of magnitude and in addition removes the microwave-induced non-resonant background. This is exemplarily demonstrated for spin-echo measurements in phosphorus-doped silicon. The modulation of the signal is achieved by cycling the phase of the projection pulse used in pEDMR for the readout of the spin state.
